Main relay is the buzz, check t-stat ground, if cranking slow, throw a jumper on it and see.

Hey chris, that could possibly be the Issue. Generally when they go bad it could be because one of the connections inside may need to be soldered. Just to cancel that out of the list of possibilities, take it out and open It and solder everything once over or whatever looks like it needs it. Many of these contacts can have very small to the eye fracture lines. My DA had a similar issue not too long ago.....also check any surrounding wires for any type of damage.

Most people think this would be just a waste of time and Unnecessary....in my opinion, it just crosses another possibility and ensures that part is still in good working condition either way.

Have you checked some of the wiring under the dash for damage? It could of maybe been that you moved something in there and it made contact etc. I figured I'd tell ya that because it is what happened to me...previous owner had fiddled with one or the harnesses and would almost show the same signs of what you got.

Either way just keep going....you'll find the Issue soon!!
